Hello,
First of all i apologize for my english, I'm not a guru, but this may help.
I used the definitions from Dr. Stephen Henson. I found them in the web.
Using those definitions we developped a library using C++ to handle
management, verification and delegation of Acs:
And just this code should work (at least, at this time we haven't found
problems opening Acs) with the code I have attached
X509AC *ac;
ac = PEM_read_X509AC(fp, NULL, NULL, NULL);
Define this for other ways to open the Acs:
#define d2i_X509AC_bio(bp,x509AC) (X509AC *)ASN1_d2i_bio((char
*(*)())X509AC_new, \
(char *(*)())d2i_X509AC, (bp),(unsigned char **)(x509AC))
#define PEM_read_bio_X509AC(bp,x,cb,u) (X509AC *)PEM_ASN1_read_bio( \
(char *(*)())d2i_X509AC,PEM_STRING_X509AC,bp,(char **)x,cb,u)

Asunto: Problem while parsing attribute certificate.
Hi all,
I have made a try to parse attribute certificate by writing attribute
certificate ASN.1 structures myself after knowing that OpenSSL yet has no
support for attribute certificate. I am getting error right at the beginning
that is on d2i_X509AC(). It complains with the error message "Wrong Tag". It
appears to me that I have some mistake in my attribute certificate ASN.1
structures declarations. I am attaching the source files alongwith the
attribute certificate. OpenSSL gurus please help on this.
Regards,
Hashim Saleem
